What should my friend do about her incorrectly issued 60-day TR visa stamp in Thailand?

Hi everyone, a question about incorrect stamps. A friend of mine recently went to extend her 60 day TR visa (Swiss passport). As I understand it, thou must first get the normal 30 day extension before applying for any covid 60 day.

However, she was given a stamp for 60 days. I received 30 days with my British passport at the same immigration office in Ko Phangan (we went on the same day when everyone was doing there last minute covid extensions).

So I presume her 60 day stamp might have been an administrative error. I don’t want her to have any issues if she goes again after 60 days and attempts another extension/ or even leaves but after the time period of what the stamp should have been.

Has she been blessed by an extra 30 days? Will there be any issues if she carries on as though it is effectively a 60 day official stamp? Or is it going to cause her definite problems upon exiting or extending if she uses the 60 days as per her stamp.

Thank you so much for your helpful advice as always 🙏🥰

Edit: her 60 days was due to expire on 4th feb. she was stamped until 6th April. so she got an extra 60 days as a normal extension to her 60 day TR Visa. (the extension should normally be only 30 days).

I'm not sure why admin rejected the post. Can she rely on the stamp and carry on as though she had a 60 day extension, or will she have to go to amend the stamp to 30 days?
